Nikon Focusing Screen Type B for F-501

The Nikon Focusing Screen Type B is the standard matte focusing screen for the Nikon F-501 analogue SLR camera, also known as the N2020 in North America. Its matte surface provides a clear, uncluttered viewfinder image and allows focusing across almost the entire frame.

The Type B screen is suitable for general photography and is an alternative to the Type E version with grid lines and the Type J version with a microprism focusing aid.
